Two things come to my mind
If i add TRS i would need to take ride of the sync input, wish is usefull for reseting oscillateur phases when unison ( very cool effect). But I could also reset the phase with a note on event of the midi input wish also make sense and maby even more.
If you plug a TRS in the module and start playing, how do you get the "note on / gate" information for the reset of the system ? Because it seam to be a absolute need to control voices amplitudes etc
